Multiple-strand steel wire rope
Description:
Multiple-strand steel wire rope is made of one or more strands twisted around a steel core or fiber core in spiral motion. On its face, the production of multiple-strand steel wire rope is very simple, but in fact, there are very high technical requirements. Our factory adopts the best process line, equipped with the best equipment, is committed to the multiple-strand steel wire rope to do fine. Multiple-strand steel wire rope construction characteristics are non-rotation or slight rotation. Because of this characteristic, Multiple-strand steel wire rope is widely used in shaft lifting, lifting machinery, port handling and other fields.
1. Common structure:6×7 class,6×19(a) class,6×19(b) class,6×37(a) class,6×37(b) class,8×19(a) class,8×19(b) class,8×37(a) class,8×37(b) class,34×7 class,35W×7 class,18×7 class,18×19 class, etc.
2. Surface treatment: Oiled, ungalvanized steel wire rope, galvanized steel wire rope, coated steel wire rope, etc. (as requirements)
3. Material: carbon steel, stainless steel,etc.
4. Diameter : Customized according to customer needs.
5. Breaking load : Customized according to customer needs.
6. Packaging: Wood disc packaging, ABS shaft packaging, according to customer's specific requirements.
7. Application: shipping, large-scale lifting, ships, offshore installations and salvage, etc.
8. Certificate & Standard:
Certificate :ABS, LR, CE, CCS, BV, DNV
Standard :GB8919, GB/T 20067, ISO, ASTM, EN, JIS, etc.
1. Compact structure
2. High fatigue resistance
3. Broken pulling force of wire rope is high.
4. Highly cost effective.
5. Long service life, reduce rope replacement and shutdown loss.
Why choose our steel wire rope?
The technical requirements of multiple-strand steel wire rope are very high, and many metal products factories have the ability to produce, but their product quality is different.

Wire matching process |
Some wire rope manufacturers in order to facilitate production, wire matching process is simpler.
|
The diameter of the rope is not up to the requirements, and the diameter of the hemp core is artificially increased. In this way, the quality of the inner rope twisting can not be guaranteed, resulting in uneven stress of the whole rope.
|
According to the actual requirements of the inner rope diameter wire. Ensure that the inner rope is evenly twisted, while the outer strand is evenly twisted, ensure that there is enough gap between the outer strands. |
Prevent wire rope in the process of use between the inner strand extrusion, or even edge. Wire rope has uniform stress and long service life. |
|
|
Non-rotating |
Different structure and rough process design. |
Some multiple-strand wire rope rotation torque is large. |
Make sure the torque is as small as possible during process design. |
Ensure that the multiple-strand wire rope does not rotate or rotate slightly
|
|
|
Testing for unloose performance |
Nonstandard testing for unloose performance. |
Wire rope twisting system is not uniform, quality is not guaranteed. |
About 5 lay distances were taken from the normal part of the wire rope head, and all the outer strands were taken to measure the height of the strands. |
Make sure that the height of each strand is uniform and can be lined up in order.Ensure that the twist uniform, the tension state of the same. |
